The invention relates to a 360-degree monitoring device for a power transmission line tower, and the device comprises a camera, a main controller is in two-way communication with the camera and a communication module, the output end of the main controller is connected with the input end of a rotation control module, the output end of the rotation control module is connected with the input end of a servo motor, and the output end of the servo motor is connected with the output end of the power transmission line tower. The camera, the main controller, the communication module, the rotation control module, the servo motor and the power supply module are integrated. The invention further discloses an image splicing method of the 360-degree monitoring device for the power transmission line tower. According to the invention, the rotation of the servo motor is controlled by controlling the rotation control module to change the pulse frequency, so that the camera is controlled to shoot the image, and image matching fusion is carried out by determining the SIFT feature points of the similar areas of the adjacent images, so that the calculation amount of an algorithm for searching the overlapped areas of the spliced images is reduced, and the accuracy of image fusion is improved.
Description
technical field [0001] The invention relates to the technical field of video monitoring of power systems, in particular to a 360-degree monitoring device of a transmission line tower and an image stitching method. Background technique [0002] The power transmission and transformation lines of the power system are widely distributed and have long transmission distances. Most of them have been exposed to harsh natural conditions in outdoor sparsely populated environments for a long time. They are extremely vulnerable to various natural disasters, meteorological conditions and external damage. The stability and security of the operation have brought hidden dangers. With the large-scale application of video surveillance and the theoretical research and application of image processing and recognition technology, good application results have been achieved, but for image data, image stitching technology needs to be used to combine several images with overlapping areas into one. ...
